My Father Commands a Million Soldiers. What's Wrong with Me Abolishing the Crown Prince?

Reborn as the Northern Prince’s only son, yet a useless hostage confined in the capital? The Crown Prince steals my woman, the other princes treat me like a dog, and the entire court laughs that my father’s achievements have made him a threat to the throne! Su Chen laughed. This time around, he was determined to be the wildest playboy alive! He pointed his sword at the emperor in the Golden Hall. “Your Majesty, please depose the Crown Prince!” He beat up his own beloved in public and extorted the officials. The emperor issued an edict in the middle of the night: “Please go handle the disaster relief!” The flood victims of Xihe knelt to welcome him, enemy assassins trembled in fear, and even the cold, beautiful princess traveling with him panicked. “What exactly do you want?” Su Chen toyed with the imperial jade seal and robe, his voice languid. “Simple. Either the empire takes the Su surname, or... my father brings his army here to take it himself.”
